This Earth Day NASA’s Digital Learning Network (DLN) joined with the MAGPI group to explain how the Landsat program has helped scientists observe our planet since 1972. Landsat satellites have enabled people to study many aspects of our planet and to evaluate the dynamic changes caused by both natural processes and human practices. Students and teachers were able to talk with NASA scientists and engineers from Goddard Space Flight Center via live web connections.
The Landsat Education and Public Outreach team provided images and background resources for this event. Landsat scientists Jim Irons and Bob Bindschadler joined with Landsat engineer Terry Arvidson for event interviews. NASA’s DLN is directly tied to the Agency’s major education goal of attracting and retaining students in STEM disciplines.
